Abstract [en]

PURPOSE: To get knowledge of the work environment for seafarers sailing under the Swedish flag, in terms of safety climate, ergonomical, chemical and psychosocial exposures, and the seafarers self-rated health and work ability.

METHODS: A Web-based questionnaire was sent to all seafarers with a personal e-mail address in the Swedish Maritime Registry (N = 5608). Comparisons were made mainly within the study population, using Student's t test, prevalence odds ratios and logistic regressions with 95% confidence intervals.

RESULTS: The response rate was 35% (N = 1972; 10% women, 90% men), with 61% of the respondents working on deck, 31% in the engine room and 7% in the catering/service department (1% not classifiable). Strain on neck, arm or back and heavy lifting were associated with female gender (p = 0.0001) and younger age (below or above 30 years of age, p < 0.0001). Exposures to exhausts, oils and dust were commonly reported. Major work problems were noise, risk of an accident and vibrations from the hull of the ship. The safety climate was high in comparison with that in land-based occupations. One-fourth had experienced personal harassment or bullying during last year of service.

CONCLUSIONS: Noise, risk of accidents, hand/arm and whole-body vibrations and psychosocial factors such as harassment were commonly reported work environment problems among seafarers within the Swedish merchant fleet.

Abstract [en]

This thesis explores health hazards for seafarers in the Swedish merchant fleet, and occupational risks for lung cancer, mesothelioma and hematologic malignancy (HM). A special focus has been exposure to benzene and biomarker levels for work on product or chemical tankers during the mid-1990’ies.

In a case report, we describe two cases of mesothelioma and two cases of lung cancer having worked in the engine room. Cumulative exposure to asbestos were up to 5 fibreyears. Other exposures were carcinogenic PAHs and nitroarenes. A web-based survey to active seafarers in the Swedish merchant fleet revealed noise, the risk of accidents, whole-body vibrations and ergonomic strain as main work environment problems. General health, work ability and safety climate were all rated high. Associations were found between lower airway symptoms and soot (PR 2.4, 95% CI 1.1-5.1) and between hearing impairment and noise exposure (PR 1.5; 95% CI 1.3–1.7). Iso-strain was especially common in the service department. Twenty-two percent of men and 45% of women had been subjected to harassments. The tanker study showed a geometric mean for benzene exposure of 0.45 mg/m3 (4hTWA) during a work shift, with a wide range (0.02-143 mg/m3). Correlations were found between exposure and benzene in alveolar air (p<0.0001), unmetabolised benzene in urine (p<0.0001) and ttMA in urine (p=0.0011). All biomarkers increased significantly during work (p<0.002). In a case-referent study with the observation period 1985 to 2014, the OR for HM was 1.32 (95% CI 0.86-2.02) if work on tankers had started before 1985 and with a cumulated tanker service of at least five years. If work on tankers had started after 1985, the OR was 0.85 (95% CI 0.51-1.43).

In conclusion, health hazards in today’s seafaring relate to physical, chemical and psychosocial factors. Work on tankers with mixed open and closed cargo systems might have led to important benzene up-take. Possibly, the risk for HM for seafarers on tankers has decreased during the last decades.
